Potential of Neem Leaf Powder as Bio Adsorbents for Dye Colour Removal

In this study, two types of eco friendly and low cost bio adsorbents, Neem leaf powder NLP and acid treated Neem leaf powder TNLP were prepared for the removal of dye color from Congo red solution. The physicochemical parameters of the prepared absorbents were measured. The structural features of these absorbents were analyzed by FTIR, XRD, and SEM. These experiments were conducted with different process parameters such as adsorbent dosage and agitating time using batch adsorption method. Firstly, the dosage amount of adsorbents was optimized for constant shaking for one hour and it was observed that the maximum percent adsorption was found at 91 of 0.4 g for NLP and 76 of 0.4 g for TNLP. The optimum dosage amount of adsorbents, 0.4 g was selected for further study. After optimizing the adsorbent dosage, the optimum agitating time was observed at 60 min with the percent removal of 91 for NLP and 76 for TNLP. From this research, it was observed that NLP and TNLP can be used as bio adsorbents to remove the color of the dye solution.
